Objective: In order to provide guidance for the prevention and control of epidemic situations in schools, this paper explores the risk perception and prevention behaviors of college students after classes resume in the post-epidemic period of novel coronavirus pneumonia. Methods: By using convenient sampling method, 835 college students who resumed classes were randomly selected from a university in Guizhou. Self-efficacy questionnaire, perceived social support questionnaire and self-designed questionnaire were adiministered. Results: Totally 37.0% of college students believed that the risk of infection was high, 57.4% of college students believed the severity of infection was very high once get infected, meanwhile, 84.3% of them think that keeping away from crowded places was a better preventive behavior, 89.7% of college students often wear masks, 91.4% of college students wash their hands frequently. There was a significant positive correlation between general self-efficacy, perceived social support and preventive behavior (r=0.10-0.65, P<0.01). General self-efficacy and perceived social support play both a partial intermediary role and a chain intermediary role between risk perception and preventive behavior. Conclusion Risk perception of Novel Coronavirus was moderate among college students, who can take active measures to effectively prevent it. Risk perception could not only directly affect the prevention behavior of college students, but also indirectly affect the prevention behavior of college students through understanding social support and general self-efficacy.

Objective:To explore the effect of gemcitabine-associated thrombocytopenia on the survival time of patients with ad-vanced non-small cell lung cancer (NSCLC).Methods: The data of patients with advanced non-small cell lung cancer treated with gemcitabine from January to December 2011 were retrospectively collected. According to the lowest platelet (PLT) value of the first treatment of gemcitabine,the patients were divided into two groups,PLT higher than 50 × 109·L-1group(43 cases) and PLT lower than 50 × 109·L-1group(24 cases). The survival time was retrieved by referring to the electronic medical records. The relevant in-dices in the two groups were compared and analyzed by COX multiple factors. Results:A total of 67 patients were enrolled in the stud-y. Except for the pathological type,there were no significant differences in gender,age and chemotherapy cycle between the groups(P>0.05). There was significant difference in the survival time between the groups (P<0.05). The median survival time of the pa-tients with PLT higher than 50 × 109·L-1was significantly longer than that of the patients with PLT less than 50 × 109·L-1. Con-clusion:Compared with the patients with mild thrombocytopenia(I/II),gemcitabine induced severe thrombocytopenia(III/IV) in the patients with advanced non-small cell lung cancer(NSCLC) has effect on the survival time of the patients. Therefore,it is necessary to do a good job in the prevention and treatment of thrombocytopenia.

Objective: To explore the effectiveness of machine learning algorithms in predicting non-suicidal self-injury (NSSI) behavior among college students, and to analyze the influencing factors of NSSI behavior, thus providing a reference for promoting psychological well-being. Methods: In December 2022, a stratified random cluster sampling method was used to select 835 college students from a university in Guizhou Province, China. The Adolescent Self-injury Scale, Family Function Assessment Scale, and Emotion Regulation Self-efficacy Scale were used to evaluate the participants. Demographic characteristics, family factors, and emotional factors were taken as independent variables, while the dependent variable was whether college students exhibited NSSI behavior. Machine learning algorithms, including Logistic regression, support vector machine (SVM), decision trees, algorithm gradient boosting trees, random forests, and AdaBoost, were used to construct predictive models. Results: The detection rate of NSSI behavior among the college students was 23.23% (194 individuals). The NSSI behavior group scored higher than the non-NSSI behavior group in total family function, emotional communication, egoism, and family rules ( t=3.02, 3.35 , 2.23,2.87, P <0.05). On the other hand, the non-NSSI behavior group scored higher than the NSSI behavior group in total emotion regulation selfefficacy, managing negative emotion self-efficacy, and expressing positive emotion self-efficacy ( t=-5.04, -5.48 , -2.43, P <0.05). The recall rates of random forests, SVM, Logistic regression, decision trees, algorithm gradient boosting trees, and AdaBoost were 84.3% , 90.6%, 73.4%, 87.5%, 95.3%, 89.0%, respectively. The F1 scores were 84.4%, 92.1%, 71.2 %, 79.4%, 91.7%, 89.1% , respectively. The respective precision rates were 84.4%, 93.5%, 69.1%, 72.7%, 88.4%, 89.1 %. The AUC scores were 0.845, 0.922, 0.706, 0.776, 0.915, and 0.891, respectively. Conclusion Compared to the algorithm gradient boosting tree, random forest, Logistic regression, and AdaBoost models, the SVM model has a better predictive effect on whether college students in Guizhou Province exhibits NSSI behavior. It is recommended to use an appropriate model to identify students at risk of NSSI behavior as early as possible and provide psychological crisis interventions to promote their mental health.

RNF20, an E3 ligase critical for monoubiquitination of histone H2B at lysine 120 (H2Bub), has been implicated in the regulation of various cellar processes; however, its physiological roles in adipocytes remain poorly characterized. Here, we report that the adipocyte-specific knockout of Rnf20 (ASKO) in mice led to progressive fat loss, organomegaly and hyperinsulinemia. Despite signs of hyperinsulinemia, normal insulin sensitivity and improved glucose tolerance were observed in the young and aged CD-fed ASKO mice. In addition, high-fat diet-fed ASKO mice developed severe liver steatosis. Moreover, we observed that the ASKO mice were extremely sensitive to a cold environment due to decreased expression levels of brown adipose tissue (BAT) selective genes, including uncoupling protein 1 (Ucp1), and impaired mitochondrial functions. Significantly decreased levels of peroxisome proliferator-activated receptor gamma (Pparγ) were observed in the gonadal white adipose tissues (gWAT) from the ASKO mice, suggesting that Rnf20 regulates adipogenesis, at least in part, through Pparγ. Rosiglitazone-treated ASKO mice exhibited increased fat mass compared to that of the non-treated ASKO mice. Collectively, our results illustrate the critical role of RNF20 in control of white and brown adipose tissue development and physiological function.
